1. Objectives:

（1）          Understand the main concepts and importance of Human Parasitology in basic and clinical medicine, and how to study the course content.

（2）          Understand the harmfulness of parasitoses to humans, the status quo of parasitoses in our country and the grand achievement we have accomplished in the course of parasitoses control.

（3）          Master some concepts: parasitism, parasite, host. Master life cycle, infective stage and infective route of parasites. Master the relationship between a parasite and host. Master the immune reaction to parasitic infection.

（4）          Become familiar with the general rules and the features of parasitoses spreading and prevention of parasitoses.

2. Contents:

（1）         Concepts of parasitism , symbiosis, mutualism, commensalism , parasite and host. 

（2）         Classification of parasite: endoparasite; ectoparasite; obligate parasite; facultative parasite; opportunistic parasite.

（3）         Classification of final host or definitive host; intermediate host; reservoir host; paratenic host

（4）         Life cycle, infective stage and infective route of parasites.

（5）         The relationship between parasite and host

1) Pathogenic effects of parasites: physical trauma; taking nutrition from the host; chemical damage

2) Defensive effects of the host: innate immunity; acquired immunity ( sterilizing immunity, non- sterilizing immunity ); immune evasion.

3) The outcome of interaction between host and parasite：

（6）         Epidemiology and prevention of parasitoses.  parasitic infection；carrier；parasitosis（parasitic disease）; the harmfulness of parasitoses,  the status quo of parasitoses in our country and the grand achievement we have accomplished in the course of parasitoses control; the manner of transmission; general rules in the prevalence of parasitic diseases.
